This large surface area facilitates the reduction of iron ore to DRI; however, it is prone to generate significant fines during handling and storage and encourages reactivity with oxygen when exposed to air and water. Therefore, CDRI must be kept dry to prevent oxidation (rusting) and loss of metallization. HOT DRI (HDRI)
